CANARY Cardboard Cutter with Sheath - 7.5" Box Opener Utility Knife with Non-Stick Coated Blade for Breaking Down Boxes & Opening Packages - Made in Japan, Yellow

I’ve had this for about a year now, and it’s become part of my daily routine. We receive a constant stream of deliveries, which means plenty of boxes to break down, and this tool has handled all of it with ease. I picked it up after getting tired of ruining scissors, pocket knives, and razor blades with sticky packing tape. The non-stick blade is what really sets it apart. Adhesive never builds up, and I’ve never had to wipe it off or clean it. It cuts just as well now as it did when it was brand new. It isn’t sharp at all, which makes it very safe to use, yet the serrated edge still cuts through cardboard easily and efficiently. The size is just right. At around 7.5 inches, it feels comfortable in hand and easy to control without feeling awkward or bulky (or too small for that matter) Overall, this has been a solid purchase. It does exactly what it’s meant to do, stores easily, and feels genuinely designed for everyday use. If you’re looking for a reliable box cutter that holds up over time, this one is an easy recommendation.

I've been using the CANARY Cardboard Cutter for a few weeks now, and I have to say, it’s become my go-to tool for opening boxes and packages. First off, the serrated blade is super sharp, and it slices through cardboard like butter. I love that it’s made from Japanese stainless steel, which feels sturdy and reliable. One of my favorite features is the non-stick coating on the blade. I didn’t really think much of it at first, but it actually makes a difference! You know how sometimes tape and glue can get all stuck on the blade? Not with this one! It cuts cleanly every time, which is a big plus in my book. The size is just right—7.5 inches is easy to handle without feeling bulky. Plus, it comes with a sheath that keeps the blade covered when I’m not using it, so I can toss it in my drawer or bag without worrying about accidental cuts. I mean, who wants to deal with that? Now, for the downsides: the only thing I noticed is that the sheath can be a bit tricky to get on and off at times. It’s not a deal-breaker, but it could be a bit smoother. Also, it might not be the best choice for those who need a heavy-duty cutter for tougher materials. Overall, I’m really happy with this purchase. If you’re looking for a reliable box cutter that’s easy to use and safe to store, I highly recommend giving this one a shot. Five stars from me!

In addition to being the best and safest knife to carve jack o'lanterns, these are great for kids just learning the basics of how to use a knife or box cutter, with little to no chance of cutting oneself. These are ideal for opening boxes and packaging in cold environments, even with gloves on. Highly recommended.

It came in a cardboard box. I tested the knife on the box once I opened it and it shredded the cardboard into small bits with no fuss and minimal cardboard dust. It’s also completely safe to touch in case you are worried about safety in any way.

This is a nice tool to have if you cut up a lot of cardboard. But I think after using it a box cutter would be a lot quicker. However, you can make precise cuts if you need to like cutting circles out for a hand holds or for animals to play inside. You still have to make a sawing motion to cut which is where you would slow down compared to a box cutter. I have a feeling that the box cutter blade will dull quicker than this ever will.

Cut through cardboard like butter. Can't cut yourself unless you apply a lot of pressure. Very safe to use.

Excellent for boxes . Safe to use

I buy way too much stuff on Amazon and end up with several boxes that need to be cut and flattened before I dispose of them. I’ve generally used some pocket knives which are on the more expensive side but I know cardboard ruins the edge. I don’t like the standard cutters that use razor blades. Then I found this. Made specifically for cardboard and made in Japan so you know its quality. From first use, I loved it. The serrated blade works perfectly. Isn’t super sharp in the sense that it won’t cut your hands. Nice and lightweight and has a solid build to it with a nice blade cover. Highly recommended if you deal with a lot of cardboard.

These things are awesome! Cuts cardboard like butter and a ton safer and easier than a box cutter knife. I use them with my kids for cardboard crafts. They are **not** safe for young kids to use unsupervised though. You can get a nasty cut if your not careful. They're dull to the touch but become very sharp when sawing or slicing things quickly.

ハロウィンのカボチャを掘るために購入しました。 軽くて持ちやすく、使いやすかったです。 これまではナイフで掘っていましたが、これだとあまり危なくなくてありがたかったです。 ダンボールももちろんよく切れます。 開けるのにも、分解するのにも重宝しています。 子供のダンボール工作にも使えています！

These are FABULOUS. So efficient and safe and perfect. Japanese engineering 100%

ダンボールがザクザク切れる。 ハサミでチマチマ切っていたのがバカらしく感じるレベル。非常に満足。

These work quite well cutting through cardboard with little risk of slicing yourself!
